Norgren KM/8025/M/125 Cylinder - ISO 6432 Certification
Part Number: KM/8025/M/125
Quick Summary
Norgren KM/8025/M/125 cylinder provides precise, stainless-steel actuation for compact food-grade automation. In demanding environments, engineers wrestle with corrosion, downtime, and inconsistent cushioning that disrupts lines. The KM/8025/M/125 conforms to ISO 6432, offers high corrosion resistance, and uses a magnetic piston for reliable sensing in hygienic plants. Its design supports food-processing, packaging, and clean-in-place workflows with standard G1/8 ports and a 25 mm bore. Combined with feet or rear mounting options and Pneufit 10 compatibility, it reduces downtime, simplifies installation, and lowers total cost of ownership. In practice, this translates to longer maintenance intervals, consistent cycle speeds, and predictable performance across the most demanding automated lines.

Stainless steel construction delivers exceptional corrosion resistance for demanding washdown and hygienic environments, extending service life in food and beverage lines. This 25 mm bore, 125 mm stroke cylinder is built to endure caustic cleaning cycles while maintaining consistent actuation performance. The combination of material choices and a sealed design translates into lower maintenance costs and fewer unplanned outages over the lifecycle. The magnetic piston is standard, enabling reliable, non-contact position sensing that simplifies integration with PLCs and sensors. In practice, this means fewer wiring errors and quicker diagnostics on automated lines, especially when combined with the M/50/LSU/5V reed switch and QM mounting brackets. Double-acting operation with buffer cushioning delivers controlled deceleration at stroke ends, reducing mechanical stress on conveyors and grippers. This results in smoother cycling, improved repeatability, and greater throughput on packaging and handling equipment. ISO 6432 conformance ensures compatibility with a broad ecosystem of pneumatic components, while the G1/8 port size aligns with standard Pneufit 10 fittings for fast, tool-free assembly. Base materials – barrel in X5 Cr Ni 18 10 and piston rod in X10 Cr Ni S 18 9 – provide robust corrosion resistance and cleanability, meeting hygiene expectations in food and pharma environments. Flexible mounting options, including foot mounting (M/P72404), rear hinge mounting (KQM/8020/24), and piston rod clevis mounting (KQM/55433/25), simplify installation on retrofit projects or new lines. The 1–10 bar operating range supports a wide variety of compressed air systems, while the standard 25 mm bore and 125 mm stroke fit many existing cells. Optional sensing solutions exist with Pneufit 10 fittings and compatible switches, enabling modular integration into control architectures without custom hardware.

FAQs
KM/8025/M/125 uses standard G1/8 ports and Pneufit 10 push-in fittings, which speeds field installation and reduces the need for custom adapters. Mounting options such as foot mounting (M/P72404) or rear hinge brackets (KQM/8020/24) simplify installation in tight spaces. Plan for a 125 mm stroke and ensure the compressed air supply delivers 1–10 bar to maintain consistent cylinder speed and stroke length, reducing misalignment and premature wear.
The 25 mm bore and 125 mm stroke provide ample travel for pushers and clamps while keeping the unit compact. The double-acting design with buffer cushioning yields smooth deceleration at end stops, minimizing mechanical shock to conveyors and grippers. Expect improved cycle consistency, reduced maintenance needs, and higher throughput on packaging and handling equipment.
Yes. The stainless steel barrel and high corrosion resistance suit washdown and hygienic environments common in food and beverage processing. The magnetic piston supports reliable sensing in clean rooms, and ISO 6432 compatibility ensures broad integration with standard pneumatic components used in hygienic production lines.
The datasheet notes ISO 6432 conformance and materials suitable for food-related environments. There are no explicit SIL, CE, or IP rating details provided. For regulated applications, verify with the supplier and request documentation or a certificate of conformity to confirm compliance for your specific regulatory needs.
Durable stainless steel design and buffer cushioning extend service intervals, reducing downtime. Magnetic piston simplifies sensor integration and diagnostics, lowering wiring and wiring-related failures. Standardized mounting and fittings speed retrofits and installations, delivering faster time-to-value and predictable performance on high-use lines.
